1 UNITED 5m 'YORK PATENT; OFFICE JOHN srvwATERMAN, OF. SOARSDALE, NEw YORK, ASSIGNOR T BELL. TELEPHONE LABORATORIES, INCORPORATED OF ,NEW YORK,. N..Y., A. CORPORATION OF IVE-W Application filed June 19,

This invention relates to improvements in apparatus for producing artificial respiration, and more particularly to resuscitators of the type shown'in Patent No. 1,609,659.

' The "object ofthe present invention is to overcome objections heretofore present in apparatus for. mechanlcal resuscitation, by pro viding an improved device which will pro duce the Schaefiermethod, which at the present time no device of this nature actually accomplishes. Y

Heretofore, in apparatus for producing artificial, respiration,.it has been common practice to provide in such devicesa means for exhausting the lungs which exerts a' down- Wardpressure approximately in the small of methodoi artificial respiration and is in er:

7 paratus for artificial. respiration which ac- :Eect'nothingmorethan a bellows action. I

Applicant has therefore devised an. ap-' tually operates in accordance with the Schaet.

fermethod of artificial respiration, byproviding not only a downward pressure to the diaphragm of thepatient but also a kneading or forward motion, which when practicing the Schaefi'er method, is done with the hands. Applicant has provided his device with a means for imparting this kneading motion which is very essentialto the successful practicing ofthe Schaefi'er method. 2 p

'In order that my invention may be more readily understood, 1 have'illustrated, by

Way of example, an embodiment thereof in the accompanying drawings, of which:

arms;

Fig. 4 is an enlarged detailed view of the padswhich are secured to the belt;

' Fig. 5 is a side elevation of a modified form of pressure pad; and t Fig. 6 is aview in cross section of Fig. 5.v Referring now to Figs. 1 and 2, the improved devioe comprises an inclined portion 10 for supportingthe chest of the patient and is constructed out'of sheet metal or some other j suitable material. Thelower end 11 of the inclined portion 10 is arranged to rest on the ground" while the higher or opposite end 12 is raised a sufficient distance from the ground to give it the proper slope and is supported by means of the side members 13. Located on the inclined portion 10 is a suitable pad 'l'tof resilient material upon which 'thepatients chest'is supported. In order that the patients head 22 may be suitably sup- 1 ported there isprovided a rest 15 which is curved to accommodate thepatients' forehead 23. This curved plate 15 is loosely mounted on the yoke 16 which inturn is socured to the bracket arms17 and 18 which are rigidly secured to the ends of the side I members 13. Dueto this constructionthe patients head issupported clear of the upper end 12. V 7

Located atthe upper end 12 of the inclined portion ldand hinged thereto are a pair of fin'shap'ed supports 19 and 20. These sup ports are so shaped as to fit conformably against the front of the patients shoulders 21 and extend beyond his armpits and fit' closely against his sides. These supports are arranged to be operated inwardlyand outweight- At the same time as thelevers25 means of the devices29 and. 30,- andcom-- prises two portions which may be adjustably secured by means ofithe aforementioned devices 29 and 30. Secured on the inside surface of the belt portions 27 and 28are the hinged plates 31, (see Fig, Mounted on.

these hingedplates, one oneitlier side ofthe hinged Joint 32' are the members 33 and; 34

which when the belt is secured in positionaround: the patient, are arranged to-fit into the body and'exert'pressure in the same man,

ner as e human hands whenpracticing the S'chaefier method of artificial respiration.

The lower end: of tliehingedpl'ates 31 are so formed'that they fit around. the lever. arms 351and'clamp the belt portions 2728 there-. on. The belt. 27-28 may be adjustedfandsecured in position. onv thelever arms' 35 by means of thumb nuts 36 which are threaded. in the curvedportio'n of the plates31 and engage the lever arms 35.

The lower ends of the lever arms3'5 are pivotally securedltothe side members 13by means ofthe studs-37, and the links 38andat their upper ends by means of the studs39'tand the, bell; crank levers 40, the bell crank levers 40*i'n turn being secured. tothe projecting arms25by. means of the studs 44 1. whichare slidably mounted in the, slots 42. It is tlius readil apparent that any movement: trans-v mittedyto thehandle 46. willbe transmitted'to the lever arms 35 and. inturnto the belt 27 -28,;

Due. to; the, above arrangement and. con: struction it can be readil'y'observed' that .not

only. is a downward movement imparted to the Belt 2728 but. alsoa forwardmovement, as well,.as shown in Fig. 3. This downwardandforward movement is duetothe shape of the arms, 35; the, links 38andthebell crank levers 40; and'al'so due to the fact that the belt 27-28with,its raisedportions or pads 33 and 34. are rigidlysecuredto the lever arms 35 so that; there is noslippage and no loss of mo tion.

When the handle or frame 46 is graspedfand.

outwardly, at. the, sametime, thereby causing thepatients shoulders 21. to drop of their; own

areoperated,.the lever; arms-35 are alsooperated and; are forced downwardly and for? *wardly, thereby causing. the belt 2728 to" exert a downward and forward pressure on the patients body at the same time. Due to this motion and the raised portions or pads 33 and 34 on the belt 27*28, a so-called kneading efiect will be roduced, which is anessentia-lpart of the chaefi'er method of resuscitatiom.

The handle 46 is returned to its upper or normal position by means of springs (not shown? located; on'e'the under. side of thGXllI: clinedi portion; 10; The upward: motion. of the handle 46 releases the pressure oflthehelt 27T-28 and slides ithbackitoits normal position. I

In-Figs. 5 and fi a modified form of pad is illustrated which comprises two members, namely, an upper member 43' and a lower member 445 these two members are held in. spaced relation by meansof" the sprin s the lower member 44 is arranged to e secured to the metal plates 31, whilethe'upper member. 43' is" resiliently sup ortedi dhe 13b theaction of the springs 45. his typeof iresilient pad when brought into contactwlth. the body of" the patient will readily lend tself'to any irregularities of the bodysanddue to its resiliency will obviate anychahceof abrasion.

The apparatus as heretofore describedienables an unskilled'person to practiceandcorrtinue f'or long periodsoftimewithout fatigue the so-called Schaefler method of respiration.
